Same arrows and the Blazers are a little lighter in weight.
Anyway, did some tiller tuning at 40 and 50 yards this evening, got the Blazers to group as well as the Easton Diamonds, and all it took was 1/4 turn of a limb bolt.
Yep. By changing the tiller you changed the way the a$$ end was coming out of the bow. The 4" vanes came out lower than the blazers. Your foc was different.
